What is SIP Trunking? and How Does It Work?

SIP, or Session Initiation Protocol, is the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network. A SIP Trunk can support multiple voice calls or voice channels, routed over an IP network such as a MPLS Network or Internet. Unlike traditional telephony where clusters of physical wires are delivered from the service provider to a business, a SIP trunk eliminates the need for analog connections, by replacing fixed Public Switched Telephone Network (PSTN) lines with a flexible, feature-rich system with full PSTN connectivity.

How Does SIP Trunking Work?

SIP Trunks replace fixed Public Switched Telephone Network (PSTN) lines with a flexible, feature-rich system with full PSTN connectivity. Unlike traditional ISDN Trunking, PRIs, or analog circuits where clusters or bundles of physical wires are delivered from a traditional service provider, SIP Trunks can be added or subtracted individually to meet the particular business phone needs for any company.

SIP Trunks are a popular business phone system solution because of the many benefits offered by SIP service, including cost savings, high reliability, rich features, security, and flexibility.
